Nasal polyps are benign neoplasms in the nasal cavity. Pathologically, nasal polyps are benign tumors. Clinically, the primary treatment is the surgical removal of nasal polyps followed by regular outpatient follow-ups to prevent recurrence. Currently, the surgery for nasal polyps is generally performed under general anesthesia, involving the removal of nasal polyps and sinus opening procedures, which are functional surgeries. Such surgeries require hospitalization and are conducted under endoscopy, typically under general anesthesia. Although in some regions, the surgery may be performed under local anesthesia, hospitalization is still required for the procedure, and it is generally not conducted on an outpatient basis.
